Allison Ashley-Koch, PhD, is a Professor in the Section of Medical Genetics,
Department of Medicine at Duke University Medical Center. She received her
Ph.D. in genetics and molecular biology from Emory University. Dr. Ashley-Koch
is a genetic epidemiologist whose primary goal is the identification of genes
that contribute to human genetic disorders, including gene-gene and gene-environment
interactions. Much of her work focuses on disorders of a neurological or psychiatric
nature. She is examining the genetic, epigenetic and environmental contributions to
neural tube defects (NTDs), including
anencephaly and spina bifida. One of the NTD projects is aimed at understanding the
connection between fumonisin exposure and the occurrence of NTDs in Guatemala. Dr.
Ashley-Koch is also studying the genetic etiology
of Chiari type I malformation,
with or without syringomyelia (CMI), a condition often
misdiagnosed because of the clinical presentation. The CMI team is using MRI measurements
and gene expression profiles to help identify clinically and genetically homogeneous
subsets of Chiari patients. Dr. Ashley-Koch has several psychiatric genetic studies
that are also on-going, including autism, ADHD,
bipolar disorder, depression and post-traumatic stress disorder. A long-standing interest
has been the identification of genetic modifiers for
sickle cell disease (SCD).
Despite the commonality of the sickle cell mutation, there is a wide range of clinical
severity in the disease and her group is identifying the genetic risk factors for these
complications. Additionally, she is part of larger, collaborative efforts to examine the
genetic contributions to birth defects through the Duke Taskforce for Neonatal Genomics,
as well as risk for primary open angle glaucoma
and non-alcoholic fatty liver disease. Dr. Ashley-Koch's
lab is taking a variety of molecular approaches to dissect these diseases, including
next generation sequencing technologies, epigenetic methods, genomewide SNP analyses
and candidate gene mutation analysis. She works in collaboration with the
for Human Disease Modeling using zebrafish models to dissect the pathologic consequences
of human disease genes. Dr. Ashley-Koch is also interested in statistical methods
development to reduce dimensionality and to identify underlying substructure in genetic
data sets. She does this in collaboration with Dr. David Dunson in the Duke Statistics Department.
Dr. Ashley-Koch's administrative efforts include serving as Director of Graduate Studies for the
Duke University Program in Genetics and Genomics, and
Chair of the Scientific and Education Advisory Board for the
Chiari & Syringomyelia Foundation, Inc.
